Question

Which of the following plots may represent the thermal energy produced in a resistor in a given time as a function of the electric current

  1. a    
  2. b    
  3. c    
  4. d    

The correct answer is: d


    U proportional to i to the power of 2 end exponent comma hence the graph between U and i is parabolic in nature and should be above graph (b).

    Three wires of copper, iron and nickel are joined to form three junctions as shown in Fig. When the temperature of junction 1 is kept 5 0 to the power of o end exponent C with the other two junctions at 0 to the power of o end exponent C, the sensitive galvanometer gives a deflection of 14 divisions. When the temperature of junction 3 is kept 5 0 to the power of o end exponent C comma with the other two junctions at 0 to the power of o end exponent C comma the galvanometer gives a deflection of 11 divisions. Then the deflection given by the galvanometer, when temperature of the junction 2 is kept at 5 0 to the power of o end exponent C comma with the other two junctions at 0 to the power of o end exponent C comma will be
